Description

【0001】
本発明は、調整器ケーシングを備えた流量調整器であって、前記調整器ケーシングが通流通路内に、弾性材料から成る環状の絞り体によって周面係合された制御ピン又は制御円錐を有しており、前記絞り体が、この絞り体自体とケーシングに固定された少なくとも1つの構成部材との間で制御ギャップを制限しており、この制御ギャップの通流横断面が、通流時に形成される差圧下で変形する絞り体に基づき可変であり、制御ギャップが絞り体と、通流通路を制限する調整器ケーシングの内周面との間にも、絞り体と制御ピン又は制御円錐の外周面との間にも設けられており、調整器ケーシングの内周面にも、制御ピン又は制御円錐の外周面にも、周方向で互いに間隔をおかれ且つ通流方向に向けられた調整切欠きが設けられている形式のものに関する。
【0002】
このような形式の流量調整器は、時間単位毎に要求される通流量を激しい圧力変動においてもできるだけ一定に保てるようにするために、例えば水道管内で使用される。
【0003】
従来公知の流量調整器は調整器ケーシングの通流通路内に、弾性材料から成る環状の絞り体によって周面係合された、円錐形にテーパされた制御ピンを有している。前記の環状の絞り体は、この絞り体自体とケーシングに固定された構成部材との間で制御ギャップを制限しており、この制御ギャップの通流横断面は、通流時に形成される差圧下で変形する絞り体に基づき可変である。この場合、制御ギャップを制限するケーシングに固定された構成部材の周面には、周方向で互いに間隔をおかれ且つ通流方向に向けられた調整切欠きが設けられている。
【0004】
このように、調整切欠きが調整器ケーシングの内周面に設けられており、場合によっては中心の通流孔が存在している流量調整器は既に公知である。しかし、これらの従来公知の流量調整器は、時間単位毎に通流する液体量が完全に一定には保たれず、圧力の上昇に伴って僅かに増大するという欠点を有している。
【0005】
調整切欠きを制御ピンの外周面に有する流量調整器も既に公知である(例えばドイツ連邦共和国特許出願公開第4041116号明細書参照)。これらの公知の流量調整器は、要求された通流量を比較的低い液圧において達成するという点において優れてはいるが、圧力上昇時に再び減少する、通流目標値を著しく上回る通流最大値がしばしば生ぜしめられる。
【0006】
ドイツ連邦共和国特許出願公開第2131117号明細書に基づき既に公知の流量調整器の弾性的な絞り体は、水圧に関連して軸方向でも半径方向でも対応する調整面に対して押圧される。更に、この従来公知の流量調整器の弾性的な絞り体は成形された中心の制御ピンに周面係合している。また更に、前記の弾性的な絞り体は若干の盆状の凹所を備えたショルダ面に載置されている。これらの盆状の凹所は、低い吸込圧力において付加的な液体量が調整器ケーシングの内周面に沿って弾性的な絞り体の下方を通流できるようにする。更に、前記ショルダ面に設けられた凹所は、弾性的な絞り体を未だ絞り作用を有さない状態で波状に成形された制御ピンに進入させる。それというのも、差し当たっては弾性的な環の前後でその進入及び変形に必要とされる差圧を形成することができないからである。吸込圧力の上昇に伴ってようやく環状の弾性的な絞り体はシール作用を以て埋まる程度にショルダ面の盆状の凹所に押し込まれ、これにより調整に必要な差圧を発生させることが可能である。
【0007】
軸方向制御面及び半径方向制御面を時間的にずらして負荷することにより、従来公知の流量調整器を以て既に比較的低い予圧において要求された調整水量が得られる。しかし、最大通流量は前記の従来公知の流量調整器でも、制御ピンと絞り体との間に残る制御ギャップの内法幅によって制限される。
最後に、米国特許第4000857号明細書に基づき公知の衛生組込み部材は、水道取付具の流出部開口部材に組込み可能である。この従来公知の組込み部材は噴射調整器を有しており、この噴射調整器には冒頭で述べた形式の流量調整器に前置されている。この流量調整器は弾性材料から成る環状の絞り体によって周面係合された制御ピンを有している。前記絞り体は、この絞り体自体と調整器ケーシングの内周面との間でも、絞り体自体と制御ピンの外周面との間でも制御ギャップを制限しており、この制御ギャップの通流横断面は、通流時に形成される差圧下で変形する絞り体に基づき可変である。この場合、調整ケーシングの内周面にも、制御ピンの外周面にも、周方向で互いに間隔をおかれ且つ通流方向に向けられた、同一横断面形状の調整切欠きが設けられている。当該の従来公知の流量調整器も、異なる液圧下で時間単位毎に所望の通流量を、目標とする通流目標値に一定に保持することはできない。
【0008】
従って本発明の課題は特に、冒頭で述べた形式の流量調整器を改良して、時間単位毎に所望される通流量を既に比較的低い液圧において達成し且つ液圧の上昇又は激しい変動に際しても事実上一定に保つ、比較的高い最大通流量を有する流量調整器を提供することである。
【0009】
この課題を解決するために本発明では、絞り体の範囲内でそれぞれ異なって成形された横断面を有する調整切欠きが設けられており、比較的低い圧力域で遮断される調整切欠きが、比較的高い圧力域で遮断される調整切欠きに比べてより大きな、絞り体に面した内法開口幅を有しているようにした
【0010】
本発明による流量調整器で、環状の絞り体の圧力に関連した変形を片側に向かってだけでなく、内側に向かっても外側に向かっても作用させて、調整切欠きの適当な流れ横断面を制御することができる。但し、本発明による流量調整器は絞り体の領域でそれぞれ異なって成形された横断面を有する調整切欠きを有している。この場合、比較的低い圧力範囲内で遮断される調整切欠きは、比較的高い 圧力範囲内で遮断される調整切欠きと比較してより大きな、絞り体に面した内法開口幅を有している。
【0011】
本発明によるこのような流量調整器は、低圧域を迅速に閉じる調整切欠きによって検出することができる一方で、絞り体が液圧によって既に極めて激しく負荷されて初めて、高圧域で遮断される調整切欠きが絞り体によって閉鎖されるという利点を提供する。
【0012】
この場合、本発明による流量調整器は、殊に高い最大通流量に対して小さな組込みサイズという点において優れている。なぜならば、絞り体が同時且つ同期的に、両側に設けられた調整切欠きに向かって変形することができ、更に、絞り体の両側にそれぞれ調整されるべき平行な水流を有する制御ギャップが設けられているからである。
【0013】
前掲のドイツ連邦共和国特許出願公開第2131117号明細書に基づき従来公知の流量調整器の中心の制御ピンには異なって成形された波状の加工成形部が設けられてはいるが、これらの波状の加工成形部は一般に均一な調整切欠きを制限しているに過ぎない。それぞれ異なって成形された調整切欠きは、当該のドイツ連邦共和国特許出願公開第2131117号明細書では設けられていない。
【0014】
調整器ケーシング22の内周面にも、制御ピン又は制御円錐の外周面にも、絞り体の領域で異なって成形された横断面を有する調整切欠きがそれぞれ設けられていることが可能である
【0015】
機能の分離及び最適化のために本発明の有利な構成では、調整器ケーシングの内周面に設けられた調整切欠きは、制御ピン又は制御円錐の外周面に設けられた調整切欠きに比べて異なって成形された横断面を有している。
【0016】
この場合、比較的大きな内法開口幅を有する調整切欠きが調整器ケーシングの内周面又は制御ピンの外周面に設けられていると有利であってよい。
【0017】
比較的大きな内法開口幅を有する調整切欠きを、比較的低い圧力においてもゴム弾性的な絞り体によって良好に制御できるようにするためには、比較的大きな内法開口幅を有する調整切欠きがほぼ円セグメント形の横断面を有していると有利であってよい。
【0018】
これに対して、特に流れ媒体の液圧が高い場合に遮断される調整切欠きは、これらの調整切欠きが比較的小さな内法開口幅を備えて、少なくとも1部分域が半円形及び/又はエッジを急峻に構成されているように設計されていてよい。
【0019】
調整切欠きの正確な設計は、環状のエラストマの弾性特性に関連して行うことができる。
【0020】
個々の特徴は、それ自体又は複数で、本発明による構成において実現することができる。
【0021】
以下に、本発明の実施例を図面につき詳しく説明する。
【0022】
図1及び図2には調整器ケーシング2を有する流量調整器1が示されている。この流量調整器1の調整器ケーシング2は、一般に例えば衛生取付具の流出部開口部材(詳しくは図示せず)又はフレキシブルなホース導管の接続用取付具に挿入可能であり、これにより、時間単位毎に要求される水量を水供給導管内の圧力変動が激しい場合でも一定に保つことができる。
【0023】
流量調整器1は中心の制御ピン4を有しており、この制御ピン4は調整器ケーシング2の通流通路3内でケーシングに固定されて保持されている。制御ピン4は弾性材料から成る環状の絞り体5によって周面係合される。図2に示したように、制御ピン4は少なくとも前記絞り体5によって周面係合される長手方向延在部の部分域において、流れ方向Pf1とは逆向きでほぼ円錐形にテーパされている。
【0024】
絞り体は、この絞り体自体と通流通路3を制限する調整器ケーシング2の内周面との間にも、絞り体自体と制御ピン4の外周面との間にも制御ギャップ6を形成しており、この制御ギャップ6の通流横断面は、通流時に形成される差圧下で変形する絞り体5によって可変である。
【0025】
図1において認識されるように、調整器ケーシング2の内周面にも制御ピン4の外周面にも調整切欠き7,8が設けられており、これらの調整切欠き7,8は、それぞれ周方向で互いに間隔をあけられており且つ通流方向Pf1に向けられている。調整切欠き7,8は流出入方向で形成されており且つ制御ギャップ6に対して開いて形成されている。
【0026】
調整切欠き8が制御ピン4の外周面に比較的大きな内法開口幅を有しており且つ流れ媒体の低い圧力条件において既に遮断されるのに対して、調整器ケーシング2の内周面に位置する調整切欠き7は比較的小さな内法開口幅を有しているので、ゴム弾性的な絞り体は、この絞り体に作用する流れ媒体の圧力負荷が高い場合に初めて、調整器ケーシング2の内周面に設けられた調整溝又は調整切欠き7へ侵入することができる。
【0027】
ゴム弾性的な絞り体5の、液圧に関連した多少なりとも著しい調整切欠き7,8への侵入によって、時間単位毎に流量調整器1を通流する水量が一定に保たれて、水圧が徐々に上昇した場合でも規定された時間単位毎の水量を上回る恐れはない。
【0028】
比較的大きな内法開口幅を備えた調整切欠き8がほぼ円セグメント形の横断面を有しているのに対して、調整器ケーシング2の内周面に設けられた、比較的小さな内法開口幅を備えた調整切欠き7は、溝底部域がほぼ円セグメント形であり且つエッジの急峻な横断面を有している。
【0029】
図3に示した線図から、流量調整器1は異なって成形された調整切欠き7,8によって調整される変形に基づき、低圧域でも高圧域でも極めて良好な一定の調整結果を得られるという点において優れているということが明らかになる。流量調整器1は、時間単位毎に所望される通流量を既に比較的低い液圧において達成し、この通流量を液圧の上昇又は激しい変動に際してもほぼ一定に保持する。図示の流量調整器の絞り体は同時且つ同期的に両側に設けられた調整切欠きに向かって変形可能であり且つ当該絞り体の両側にはそれぞれ調整されるべき平行な水流を有する制御ギャップが設けられているので、本発明による流量調整器は比較的高い最大通流量に対して小さな組込みサイズという点において優れている。
【図面の簡単な説明】
【図1】 流量調整器の調整器ケーシングの横断面図であって、この場合、流量調整器は調整器ケーシングの内周面にも、中心の制御ピンの外周面にも、周方向で互いに間隔をあけられ且つ通流方向に向けられた調整切欠きを有している。

[0001]
The present invention is a flow rate regulator provided with a regulator casing, wherein the regulator casing has a control pin or a control cone which are circumferentially engaged by an annular throttle body made of an elastic material in a flow passage. The throttle body restricts a control gap between the throttle body itself and at least one component fixed to the casing, and a flow cross section of the control gap is formed at the time of flow. The control gap is variable based on the throttle body deformed under the differential pressure, and the control gap is also provided between the throttle body and the inner peripheral surface of the regulator casing that restricts the flow passage. Also provided between the outer circumferential surface and the inner circumferential surface of the regulator casing, the outer circumferential surface of the control pin or the control cone, spaced from each other in the circumferential direction and adjusted in the flow direction also the format provided notches On.
[0002]
This type of flow regulator is used, for example, in a water pipe in order to keep the flow rate required for each time unit as constant as possible even under severe pressure fluctuations.
[0003]
Conventionally known flow regulators have conical tapered control pins that are circumferentially engaged by an annular restrictor made of elastic material in the flow passage of the regulator casing. The annular throttle body restricts the control gap between the throttle body itself and the components fixed to the casing, and the flow cross section of the control gap is under the differential pressure formed at the time of flow. It is variable based on the diaphragm that is deformed by. In this case, adjustment notches that are spaced apart from each other in the circumferential direction and that are directed in the flow direction are provided on the circumferential surface of the component member fixed to the casing that limits the control gap.
[0004]
As described above, a flow regulator in which an adjustment notch is provided in the inner peripheral surface of the regulator casing and a central flow hole exists in some cases is already known. However, these conventionally known flow regulators have the disadvantage that the amount of liquid flowing through every time unit is not kept completely constant and increases slightly as the pressure increases.
[0005]
A flow regulator having an adjustment notch on the outer peripheral surface of the control pin is already known (see, for example, German Patent Application No. 4041116). These known flow regulators are excellent in achieving the required flow rate at a relatively low hydraulic pressure, but the maximum flow value significantly exceeds the flow target value, which decreases again when the pressure rises. Is often born.
[0006]
The elastic restrictors of the flow regulators already known from German Offenlegungsschrift 2131117 are pressed against the corresponding adjustment surfaces in the axial and radial directions in relation to the water pressure. Furthermore, the elastic throttle body of this conventionally known flow regulator is circumferentially engaged with a molded central control pin. Still further, the elastic restrictor is placed on a shoulder surface having some basin-shaped recesses. These basin-shaped recesses allow an additional amount of liquid to flow along the inner circumference of the regulator casing below the elastic restrictor at low suction pressures. Further, the recess provided in the shoulder surface allows the elastic restrictor to enter the control pin formed in a wave shape in a state that does not yet have a restricting action. This is because, for the time being, the differential pressure required for its entry and deformation before and after the elastic ring cannot be formed. As the suction pressure rises, the annular elastic throttle body is finally pushed into the basin-shaped recess on the shoulder surface to the extent that it is filled with the sealing action, which can generate the differential pressure necessary for adjustment. .
[0007]
By loading the axial control surface and the radial control surface with a time shift, the amount of adjustment water required at a relatively low preload can be obtained with a conventionally known flow rate regulator. However, the maximum flow rate is limited by the inner width of the control gap remaining between the control pin and the throttle body in the above-described conventionally known flow regulator.
Finally, a hygienic built-in member known from U.S. Pat. No. 4,0010,877 can be built into the outlet opening member of a water fitting. This conventionally known built-in member has an injection regulator, which is placed in front of a flow regulator of the type mentioned at the beginning. This flow regulator has a control pin that is circumferentially engaged by an annular restrictor made of an elastic material. The restrictor restricts the control gap between the restrictor itself and the inner peripheral surface of the regulator casing, and between the restrictor itself and the outer peripheral surface of the control pin. The surface is variable based on a throttle body that is deformed under a differential pressure formed during flow. In this case, both the inner peripheral surface of the adjustment casing and the outer peripheral surface of the control pin are provided with adjustment notches having the same cross-sectional shape that are spaced apart from each other in the circumferential direction and directed in the flow direction. . The conventionally known flow rate regulator also cannot keep a desired flow rate constant at a target flow target value for each time unit under different hydraulic pressures.
[0008]
The object of the invention is therefore in particular to improve the flow regulator of the type mentioned at the outset, in order to achieve the desired flow rate per time unit already at a relatively low hydraulic pressure, and in the event of a hydraulic pressure increase or severe fluctuations. Is to provide a flow regulator having a relatively high maximum flow rate, which is also kept substantially constant.
[0009]
In order to solve this problem, in the present invention, an adjustment notch having a cross section that is formed differently within the range of the throttle body is provided, and the adjustment notch that is blocked at a relatively low pressure range is provided. The inner opening width facing the throttle body is larger than the adjustment notch that is cut off at a relatively high pressure range .
[0010]
At a flow rate regulator according to the present invention, not only toward the deformation associated with the pressure of the annular aperture body to one side, even towards the inside to act outwardly, adjustment notches suitable flow cross The surface can be controlled. However, the flow regulator according to the invention has an adjustment notch having a cross section which is shaped differently in the region of the throttle body. In this case, the adjustment notch blocked in the relatively low pressure range has a larger internal opening width facing the throttle body than the adjustment notch blocked in the relatively high pressure range. ing.
[0011]
Such a flow regulator according to the invention can be detected by means of an adjustment notch that quickly closes the low-pressure zone, while the regulation that is interrupted in the high-pressure zone only when the throttle body has already been subjected to extremely high pressure by the hydraulic pressure. It offers the advantage that the notch is closed by the throttle body.
[0012]
In this case, the flow regulator according to the invention is particularly advantageous in terms of a small built-in size for a high maximum flow rate. This is because the throttle body can be deformed simultaneously and synchronously toward the adjustment notches provided on both sides, and a control gap having parallel water flow to be adjusted is provided on both sides of the throttle body. Because it is.
[0013]
Although the control pin at the center of a conventionally known flow regulator based on the above-mentioned German Patent Application Publication No. 2131117 is provided with a wave-shaped machining part formed differently, these wave-shaped parts are provided. The machined part generally only limits uniform adjustment notches. The adjustment notches that are shaped differently are not provided in the German patent application DE 2131117.
[0014]
It is possible that both the inner peripheral surface of the regulator casing 22 and the outer peripheral surface of the control pin or control cone are provided with adjustment notches having cross sections that are shaped differently in the area of the throttle body. .
[0015]
In an advantageous configuration of the invention for separating and optimizing functions, the adjustment notch provided on the inner peripheral surface of the regulator casing is compared to the adjustment notch provided on the outer peripheral surface of the control pin or control cone. Each having a differently shaped cross section.
[0016]
In this case, it may be advantageous if an adjustment notch having a relatively large internal opening width is provided on the inner peripheral surface of the regulator casing or on the outer peripheral surface of the control pin.
[0017]
An adjustment notch with a relatively large internal opening width is used so that an adjustment notch having a relatively large internal opening width can be controlled well by a rubber elastic diaphragm even at a relatively low pressure. It may be advantageous to have a substantially circular segment-shaped cross section.
[0018]
In contrast, the adjustment notches that are blocked, especially when the fluid pressure of the flow medium is high, have at least one partial area that is semicircular and / or with these adjustment notches having a relatively small internal opening width. It may be designed such that the edges are steeply configured.
[0019]
The exact design of the adjustment notch can be made in relation to the elastic properties of the annular elastomer.
[0020]
The individual features can be realized in themselves or in a plurality according to the configuration according to the invention.
[0021]
In the following, embodiments of the invention will be described in detail with reference to the drawings.
[0022]
1 and 2 show a flow regulator 1 having a regulator casing 2. The regulator casing 2 of this flow regulator 1 is generally insertable into, for example, an outlet opening member of a sanitary fitting (not shown in detail) or a fitting fitting for a flexible hose conduit, thereby providing a time unit. The amount of water required every time can be kept constant even when the pressure fluctuation in the water supply conduit is severe.
[0023]
The flow rate regulator 1 has a central control pin 4, and this control pin 4 is fixed and held by the casing in the flow passage 3 of the regulator casing 2. The control pin 4 is circumferentially engaged by an annular throttle body 5 made of an elastic material. As shown in FIG. 2, the control pin 4 is tapered in a substantially conical shape opposite to the flow direction Pf <b> 1 in at least a partial region of the longitudinally extending portion that is circumferentially engaged by the throttle body 5. .
[0024]
The throttle body forms a control gap 6 between the throttle body itself and the inner peripheral surface of the regulator casing 2 that restricts the flow passage 3, and between the throttle body itself and the outer peripheral surface of the control pin 4. The flow cross section of the control gap 6 is variable by the throttle body 5 that is deformed under the differential pressure formed during flow.
[0025]
As can be seen in FIG. 1, adjustment notches 7 and 8 are provided on the inner peripheral surface of the adjuster casing 2 and on the outer peripheral surface of the control pin 4, respectively. They are spaced from one another in the circumferential direction and are directed in the flow direction Pf1. The adjustment notches 7 and 8 are formed in the inflow / outflow direction and are open to the control gap 6.
[0026]
Whereas the adjustment notch 8 has a relatively large internal opening width on the outer peripheral surface of the control pin 4 and is already shut off under low pressure conditions of the flow medium, Since the adjustment cutout 7 located has a relatively small internal opening width, the rubber-elastic throttle body is not the only one when the pressure load of the flow medium acting on this throttle body is high. It is possible to enter the adjustment groove or the adjustment notch 7 provided on the inner peripheral surface of the.
[0027]
The amount of water flowing through the flow regulator 1 is kept constant every time unit by the penetration of the elastic elastic throttle body 5 into the adjustment notches 7 and 8 that are more or less significant related to the hydraulic pressure. There is no risk of exceeding the specified amount of water even if the water level rises gradually.
[0028]
The adjustment notch 8 having a relatively large internal opening width has a substantially circular segment-shaped cross section, whereas the comparatively small internal method provided on the inner peripheral surface of the regulator casing 2. The adjustment notch 7 having an opening width has a substantially circular segment shape in the groove bottom region and a cross section with a sharp edge.
[0029]
From the diagram shown in FIG. 3, the flow regulator 1 can obtain a very good constant adjustment result in both the low pressure range and the high pressure range based on the deformation adjusted by the adjustment notches 7 and 8 formed differently. It becomes clear that it is excellent in terms. The flow regulator 1 achieves the desired flow rate every time unit at a relatively low hydraulic pressure, and keeps this flow rate substantially constant even when the hydraulic pressure increases or fluctuates. The throttle body of the illustrated flow regulator can be deformed simultaneously and synchronously toward the adjustment notches provided on both sides, and a control gap having a parallel water flow to be adjusted is provided on both sides of the throttle body. As provided, the flow regulator according to the present invention is advantageous in that it has a small built-in size for a relatively high maximum flow rate.

FIG. 1 is a cross-sectional view of a regulator casing of a flow regulator, in which the flow regulators are arranged circumferentially on both the inner circumferential surface of the regulator casing and the outer circumferential surface of the central control pin. It has an adjustment notch that is spaced and directed in the flow direction.
